  • the passage surrounded by the valve seat is dominated by this control body, in particular a valve disc which is formed on a valve rod, which is actuated via a transmission, for example by an electric motor, to control the amount of fluid between the inlet and outlet, so that the transmission to the electric motor forms the actuator of the control valve.
  • control valves on the flow channel housing
  • a flange having a hole pattern which corresponds to the hole pattern on the flow channel housing, so that the valve Mitteis screws can be attached to the flow channel housing.
  • This flange is usually formed integrally with the Conssteckenden housing part and at least a portion of the actuator housing of the valve.
  • Such a control valve for internal combustion engines which is designed in the present embodiment as a plug-in valve, is known from DE 10 2012 104 612 AI.
  • This control valve has an axial inlet and a radial outlet, which are formed on the male housing part.
  • the plug-in housing is formed in one piece with an actuator housing part surrounding the transmission at least on two sides, wherein a flange plate is arranged between the actuator housing part and the plug-in housing part, which is produced integrally therewith, in particular by die-casting from light metal.
  • On the flange plate to the connection flange of the flow channel housing matching screw hole pattern is formed, so that the control valve is usually secured by screws with embiage a seal on the flow channel housing.
  • a disadvantage of this design is that for each new customer who has a different hole pattern, the entire die-cast housing must be readjusted, so that for each customer, regardless of the number of new shapes for the manufacture of the valve housing are necessary.
  • the housing plate is radially surrounded by a Mattersch on which a fferenlochmuster is formed, which corresponds to a Anschlußbohrungsmuster the flow channel housing, wherein the control valve via screws, which are inserted through the lo through holes of the Studentsschflansches, attached to the flow channel housing, the control valve be manufactured as a standard component regardless of the connection bore pattern of the flow channel housing. Only the separately manufactured union flange has to be adapted. So manufacturing costs can be saved 5, while the installation remains simple and a secure seal can be ensured to the outside.
  • the housing plate, the male housing part, and an actuator housing part extending from the housing plate are a light metal cast part, wherein the circumference of the actuator housing part extending from the housing plate is smaller than the inner circumference of the coupling flange. Due to the integral nature of the housing parts assembly costs are reduced. The use of a light metal for casting enables use in areas subject to high thermal loads.5 The coupling flange can be simply slid over the base plate from the side of the actuator housing part, thus simplifying assembly.
  • an axial section of the coupling flange pointing toward the flow channel housing has an inner circumference which essentially corresponds to the outer circumference of the housing plate. Accordingly, the Base plate completely surrounded radially by the collar flange. A displacement of the valve housing is reliably avoided by positive locking in the radial direction.
  • an axial portion of the collar flange facing away from the flow channel housing has a smaller inner circumference than the axial portion facing the flow channel housing, the axial portion facing away from the flow channel housing axially abutting against the housing plate.
  • the axial passage to the flow channel housing has a smaller axial height than the housing plate. In this way, it is ensured that, when tightening the screws, the axial section facing away from the flow channel housing bears in a tensioned manner against the base plate and thus even slight movements in the axial direction are excluded. Also be avoided by this clamping the base plate on the flow channel housing radial movements.
  • a seal is arranged between the flow channel housing and the housing plate, which is elastically deformed by the attachment of the control valve by means of the inserted through the through holes of the collar flange screws.
  • the seal is a sheet-metal bead seal, whereby an insert is possible even in thermally highly locked areas.
  • the use of sheet-metal bead seals also achieves a very good sealing effect.
  • the through holes are formed in Studentsschlansch Anschraubdomen
  • the flow channel housing facing axial height measured from the axial end of the housing plate is slightly smaller than the sum of the axial height of the housing plate and the seal. This ensures sufficient clamping of the coupling flange to the base plate.
  • the tension is only on the screw-on, so that tolerance problems are avoided in particular by a delay of the flange by screwing.
  • the axial height of the Anschraubdome is greater than the axial height of the remaining circumference of the Matterschraubdome.
  • the bracing is done so only on the screw, so that tolerance problems to the base plate are avoided in particular by a delay of the flange by screwing.
  • the coupling flange is secured against loosening secured to the housing plate, so that the control valve can be inserted into the opening with the flange.
  • Such a backup can be done mechanically by screws or rivets or cohesively by welding.
  • an inlet and an outlet are formed on the plug-in housing part, wherein a control body dominates a passage between the inlet and the outlet, which can be set in motion via the actuator.
  • a plug-in valve is particularly easy to manufacture and install, since the entire valve can be pre-assembled on the valve seat prior to insertion into the flow channel housing.
  • Figure 1 shows a side view of an inventive arrangement for attachment of another control valve to a flow channel housing in a sectional view.
  • FIG 2 shows a housing of a control valve with a collar flange in perspective exploded view.
  • the illustrated in Figure 1, designed as a plug valve control valve has a one-piece valve housing 12, which is made of a light metal die-cast, but can be heomb at low gas temperatures also made of plastic. It consists of a plug-in housing part 14, which projects into a flow channel, which is delimited by a flow channel housing 18, and an actuator housing part 20, which is arranged outside the flow channel housing 18. Between the actuator housing part 20 and the plug-in housing part 14, the valve housing 12 has a housing plate 22 formed integrally with the actuator housing part 20 and the plug-in housing part 14, with which the valve housing 12 rests on a connection flange 24 of the flow channel housing 18.
  • an electric motor housing 26 is mounted for receiving an electric motor 28, which serves to drive a control body 30.
  • the actuator housing part 20 forms, together with the electric motor housing 26, an actuator housing 31 of the control valve.
  • the control valve is driven by energizing the electric motor 28, which forms an actuator 33 with a downstream transmission 32.
  • the resulting rotation of a motor shaft, not shown, is converted by the transmission 32, which is also arranged in the actuator housing 31, in a translational movement of a valve rod 34, at the end of the control body 30 is attached.
  • the control body 30 dominates a flow passage 38 surrounded by a valve seat 36, which is formed between an inlet 40 leading into the male housing part 14 and an outlet 42 leading from the male housing part 14 into the continuing flow channel, so that a flow connection between the Inlet 40 and the outlet 42 in the resting of the control body 30 on the Valve seat 36 is interrupted and is released by lifting the control body 30 from the valve seat 36.
  • This Foldsch 44 has a first to the flange surface 24 of the flow channel housing 18 facing axial portion 46 and an adjoining second axial portion 48 which is remote from the flange 24.
  • the inner circumference of the first axial portion 46 substantially corresponds to the outer circumference of the housing plate 22 or is slightly smaller. For example, a clearance fit between these components 22, 46 may be provided.

  • the height of the connecting dome 50 is slightly greater than the height of the remaining Studentsschflansches 44, whereby the force is applied during compression to avoid tolerance problems mostly about the screwing.
  • the design of the valve housing 12 can also be made so that the Einsteckgephaseuseteil 14 of the valve body 12 is made only briefly, so that the control valve dominated in the flow channel housing 18 valve seat 36 and the Einsteckgephaseuseteil 14 only one opening in Flow channel housing 18 radially largely closes.

Abstract

On connaît un dispositif de fixation d'une soupape de commande à un boîtier de passage d'écoulement (18) d'un moteur à combustion interne, comprenant une partie de boîtier enfichable (14) qui fait saillie dans un boîtier de passage d'écoulement (18), un boîtier d'actionneur (31) dans lequel un actionneur (33) est disposé, et une plaque de boîtier ( 22) qui repose sur le boîtier de passage d'écoulement (18) et de laquelle s'étendent la partie de boîtier enfichable (14) sur un premier côté et le boîtier d'actionneur (31) du côté opposé. Pour ces soupapes de commande, un nouveau boîtier de soupape doit être conçu et fabriqué de façon adaptée à chaque nouveau type de perçage de connexion du boîtier de passage d'écoulement. Pour éviter cela, l'invention propose d'entourer la plaque de boîtier (22) radialement avec une bride d'accouplement (44) au niveau de laquelle est formé un type de trou fileté (53) qui correspond à un type de perçage de connexion du boîtier de passage d'écoulement (18), la soupape de commande étant fixée au boîtier de passage d'écoulement (18) au moyen de vis (56) qui sont insérées dans des trous traversants (52) de la bride d'accouplement (44).
